WASTE-WATER FROM THE TABLE-OLIVE INDUSTRY

The flow rate and characteristics of wastewater from Conservolea variety table olive preparation factories are evaluated as functions of time. Measurements from four and observations of operation from 10 Greek factories show that: (i) 0.0007-0.19546 m3 wastewater/ton prepared olive/day are produced and (ii) the wastewaters found have suspended solids 0.05-0.39 g/l, dissolved solids 2.31-71.44 g/l, BOD, 0.24-5.44 g/l, COD 0.76-16.46 g/l, chloride 0.11-43.78 g/l and sodium chloride 0.17-72.21 g/l. The large fluctuations in these data are caused by variations in the olive purchase and sale rates, olive preparation stages among the various periods, olive preparation conditions among the various factories and the purity, ripeness and size of olive.
